Permissions Required

The extension requires the following permissions:

Troubleshooting

Extension doesn’t appear on iNaturalist pages

  1. Ensure the extension is enabled in chrome://extensions
  2. Check that “Site access” is set to “On all sites”
  3. Refresh the iNaturalist page

No spectrogram appears

  1. Verify the observation has audio content
  2. Check the browser console for [iNatSpectro] messages
  3. Try a different observation to rule out audio format issues
